The present invention relates to an automobile battery system having a multi-battery pack and a method for operating the same. According to an embodiment of the present invention, provided is an automobile battery system having a multi-battery pack, the automobile battery system comprising: an AC power generator which generates power; a first battery pack which is connected in parallel to the AC power generator, and which includes a plurality of first battery cells connected in series; and a second battery pack which is connected in parallel to the AC power generator and the first battery pack, and which has a capacity higher than that of the first battery pack; wherein a negative electrode of the first battery cells includes a negative electrode active material, and the negative electrode active material includes a carbon material in which an interlayer spacing d_(002) of a (002) surface ranges from 0.34 to 0.50 nm during X-ray diffraction measurement using CuKa.

    본 발명의 실시 예에 따른 멀티 전지 팩을 구비한 자동차 전지 시스템은 전력을 생성하는 교류 발전기; 상기 교류 발전기에 병렬 연겨뢰어 있고, 직렬 연결된 복수의 제1 전지 셀을 포함하는 제1 전지 팩, 및 상기 교류 발전기 및 상기 제1 전지 팩과 병렬로 연결되어 있고, 상기 제1 전지 팩의 용량보다 더 큰 용량을 가진 제2 전지 팩을 포함하고, 상기 제1 전지 셀의 음극은 음극 활물질을 포함하고, 상기 음극 활물질은 CuKα를 이용한 X-선 회절 측정시 (002)면의 층간 거리(interlayer spacing, d)가 0.34nm 내지 0.50nm인 탄소계 물질을 포함하는 것을 특징으로 한다.
